This was the first and most spectacular of three appearances by Jean Harlow in a Laurel and Hardy movie. She also appeared briefly in Bacon Grabbers (1929) and Liberty (1929). Because of her fond memories of working at the Roach lot, and because she had a great sense of humor, she graciously allowed Roach to use her photo in Beau Hunks (1931). Only Harlow could be a major catalyst in a movie in which she didn't even appear.
Hans Joby (aka Captain John Peters), who successfully lampooned Erich von Stroheim in this film, had been von Stroheim's double, and repeated all his nuances and characteristics.
In 1970, this became the first silent film to have a dialogue track dubbed onto it (principally by Chuck McCann), creating in effect a sound film. Music and sound effects had been added to many silent films before, but this was the first one to add speech.
The hotel lobby had previously been used in the Our Gang short Barnum & Ringling, Inc. (1928), which featured Ollie.
During filming, Jean Harlow was 18 years old.
